NEW YORK - Joan Benoit Samuelson celebrated the 25th anniversary of her Olympic victory in style yesterday, running the fastest marathon (2 hours 49 minutes 9 seconds) by a woman over 50.
“Many years ago Nike ran a campaign with me entitled, ‘There Is No Finish Line,’ ’’ said the 52-year-old Samuelson, who has never failed to break three hours nor dropped out of a race at any distance. “Twenty years ago I really didn’t understand what that was all about, but now I’m beginning to understand.’’
